Abnormal Tyre Wear

Tyre wear can stem from a number of problems. Common causes of abnormal tyre wear are due to a suspension or alignment problem or because of an internal tyre fault or incorrectly inflated tyres.

There are several different forms of abnormal tyre wear to be aware of. If you can recognise abnormal tyre wear as early as possible it removes the need to purchase a complete new set of tyres which will save you a great deal of money. Below we detail how to spot the telltale signs of abnormal tyre wear and how to remedy these issues.

The first type of abnormal tyre wear we are concerned with is camber wear. This is frequently caused by suspension misalignment, a bent spindle, or a damaged or warped spring or control arm. The strut may also be dislocated or bent which can similarly cause camber wear issues. The symptoms of camber wear are if the inside or outside edge of the tyre is showing extreme wear but if there is none or minimal wear on the rest of the tyre. The cause of this is from the tyre leaning inwards or outwards and can be resolved by four wheel alignment.

With camber wear it is necessary to thoroughly check the suspension to detect what is causing the issue with wheel alignment. The same method should be applied if you notice a pattern of feathered directional wear. This may seem like a complicated term but simply if you rub your hand across the tyre one way and it is smooth and then the other way and it is rough this constitutes feathered directional wear. This is a telltale sign of a toe wear problem and if your wheels are toed in or out with regards each other, the tread will likely scuff and this is when you will develop a feathered directional wear pattern.

A cupped wear pattern occurs where the wheel bounces up and down as you travel. When a tyre is out of balance or is not being helped due to weak shock absorbers and struts, a cupped wear pattern emerges. If you notice this pattern on your tyres it is necessary to have your wheels balanced or to replace the worn out struts or shock absorbers.

If the centre of the tread on your tyres is more worn than the shoulders the probable cause of this is overinflated tyres. When you have too much air in your tyres they bulge out in the middle and this causes uneven wear and focuses wear onto the middle of the tyre. The opposite of this is if the outside of the tyres are more worn than the centre. This is where your tyres have been underinflated and the weight has been carried onto the shoulders of the tyres causing them to wear specifically in these areas. The tip here is to regularly check that your tyres are inflated to the correct recommendations stated in your owner’s manual.
